Interestingly enough, I had no recollection of this speaker, the first offering of Renaud de Vergnette under the now famous Triangle brand, which is distributed all around the World, including here in Australia (by Audio Active Australia in Melbourne...walking distance from my day's job office in South Melbourne!).
I have found no technical information on this product released in 1983, one year before we were to introduce our own Microphase system.
What we can derive from the picture, is that the satelite is a two-way system with a cabinet that attempt to reduce standing waves AND achieve time alignement at the same time. It looks like there is also a down firing woofer.
The satelite has a much bigger volume than our SATs, but the subwoofer seems very similar in size, probably using a 17cm woofer as well.
If anybody has any more information on these speakers, feel free to tell us in the "comments"
I am trying to visit Triangle in October, and hopefullly find out more about this quite neat design.
I cannot resit but to photographically list a few more similar designs thast have appeared here and there over the years from Davis Acoustics, Wilson Audio and others. Feel free to add to the Collection!
